She appears to be carrying sabino, not roan. Roan would typically affect more of the body and not the legs or face.
Sabino is a white gene that is commonly responsible for white leg & face markings, typically with jagged or "mapped" edges. It also has a tricky habit of mimicking roan as well as overo pattern splotches (these can be very small and random or explosive).
Judging from your horse's blaze and leg markings, she is certainly carrying sabino, which would also account for the white hairs distributed throughout her coat.
Sabino, not roan ;)
(and don't go by a coggins test, as they will simply put down what the horse LOOKS like to help with identification and lack of knowledge when it comes to colors)
